ASUS has announced the ASUS Transformer Book TX300, a Windows 8 ultraportable that combines the performance and features of a fully featured notebook with the easy mobility of a tablet. At first glance, ASUS Transformer Book is a compact and powerful Windows 8 notebook with a 3rd generation Intel Core processor and high-capacity hard drive. Detach the 13.3-inch Full HD display from the notebook dock, however, and ASUS Transformer Book seamlessly transforms into a standalone Windows 8 tablet with its own 128GB SSD storage. Here's more info:

ASUS Transformer Book is the perfect choice for anyone who wants both a full featured notebook for work and a tablet for play. ASUS Transformer Book features a powerful 3rd generation Intel Core i5 or i7 processor for outstanding multi-tasking performance, together with a backlit keyboard and large multi-touch touchpad for comfortable productivity use and content creation. ASUS Transformer Book has a 13.3-inch display with scratch-resistant Corning Concore glass, and 10-point multi-touch for intuitive fingertip control with Windows 8 in both notebook and tablet modes.

With separate batteries in both the notebook dock and tablet, ASUS Transformer Book has up to five hours' battery life in full notebook mode and up to eight hours in tablet mode. Notebook mode battery life can also be increased to up to eight hours by disabling the dock's hard drive and ports, leaving the keyboard and touchpad active. Up to two weeks' standby time and two-second 'instant-on' means ASUS Transformer Book is always ready for action, too.

When it comes to entertainment, ASUS Transformer Book's 13.3" 1080p Full HD display renders movies, photos and games with exquisite clarity. IPS display technology ensures vivid and accurate color reproduction, with 178-degree wide viewing angles that keep the image bright and clear, even when seen from the side.

ASUS Transformer Book also delivers rich and immersive sound for all kinds of listening, thanks to high-quality stereo speakers in both notebook dock and tablet. Sound quality is further enhanced by ASUS SonicMaster audio technology, co-developed with Bang & Olufsen ICEpower, and MaxxAudio sound processing from Waves, recipient of a Technical GRAMMY Award(R). ASUS Transformer Book features a front HD camera and an array microphone that are perfectly suited to video chat, plus an optional 5-megapixel rear camera with 720p HD video recording.

ASUS Transformer Book features dedicated storage for both notebook and tablet modes for 'best-of-both-worlds' mobile flexibility. A choice of 320GB or 500GB hard drives offer ample capacity for industry-standard software and personal data in notebook mode, while a 128GB SSD gives blisteringly fast storage for apps, movies, music and games in tablet mode. With the main PC components housed in the tablet, and the hard drive and expansion ports in the notebook dock, exclusive ASUS High-Speed Bridge technology ensures maximum performance in notebook mode, with a high-bandwidth connection between dock and tablet that's faster even than USB 3.0.
